SPECIFICATON forming part of Letters Patent No. 698,695, dated April 29,1902.

Application iiled October 31, 1901.

T0 all whom it may concern:

Beit known that I, REINHOLD J. E1s, a citizen of the United States,residing at Two Rivers, in the county of Manitowoc and State ofWisconsin, have invented a new and useful Machine for Making Bale-Tics,of which the following is a specification.

My invention relates to certain improvements in apparatus for formingcross-head hooks on wire bale-ties, and relates more especially to thatportion of the mechanism employed for finishing and twisting the hookedends.

The principal object of the invention is to provide a simple andeconomical machine or apparatus in which a partially-formed hook may beproperly shaped and at the same time twisted to unite the free end tothe body of the wire.

With this and other objects in view the invention consists in the novelconstruction and combination of parts hereinafter described, illustratedin the accompanying drawings, and particularly pointedout in theappended claims.

In the drawings, Figure 1 is aplan View of a hook shaping and twistingmachine constructed and arranged in accordance with my invention. Fig. 2is a sectional elevation of the same, a portion of the mechanism beingshown in side elevation. Fig. 3 is a transverse sectional elevation ofthe device on the line 3 3, Fig. 1. Fig. t is a view similar` to Fig. 3,illustrating the parts in dierent positions. Fig. 5 is a transversesectional elevation on the line 5 5 of Fig. 1, illustrating theconstruction of the wire-holding vise. Fig. 6 is a detail perspectiveview of the clamping and shaping plates detached from their respectivecarrying-jaws. Fig. 7 is a sectional elevation on the line 7 7 of Fig.8, illustrating the construction of thev mechanism for effecting thepreliminary bending of the hook. Fig. 8 is a sectional elevation of thesame on the line S 8 of Fig. 7.Y

Similar characters of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

The mechanism is designed for the purpose of forming the well-knowncross-head hook on the ends of bale tie-wires, and for this purpose theapparatus is divided into two serial No. 80,695'. (No man.)

parts, one of which eifects a preliminary ing carried on arms fulcrumedto a cross-bar or pivot-pin 1S in the lower portion of the frame. In thebase 19 are arranged female dies 2O and 21, adapted to coact with thedies 16 and 17, respectively, to effect the preliminary bending of thewires. In the operation of this portion of the mechanism one or moreWires, as 00, are placed on the bed of the machine with their ends incontact with a stop 22, the wires being placed in position just beforethe die 16 descends and while the die 17 is being raised. The dies 16and 2O make a double bend in the wire to-form thefhook portion and arethen elevated. vThe die 17 then coacts with the female die 21 to effect.

the return-bend of the end of the wire, and said wires are thenfremovedfrom the machine and subj ected to the action of the' shaping andtwisting mechanism. v VThe Ywire at this stage of the Voperation is bentin the manner indicated in Fig. 6, the portions of the wire to betwisted being slightly separated from each other, asshown.

The shaping and twisting mechanism com prises a suitable frame 30, inwhich is journaled a longitudinal shaft 31, having at one end a pinion32, intermeshing with a bevelgear 33, mounted on a stud-'shaft 34 andprovided with acrank-handle v35, or it may be driven by power in anydesired manner. The relative diameters of the bevel gear and ypinion aresuch that one rotation of the bevelgear will effect three completerevolutions of the bevel-pinion, this beingthe number of twists giventhe hook end. To disengage the gears after one complete revolution of.the bevel-gear, the latter may be longitudinally movable on itscarrying-shaft and normally held in position to engage the bevel-pinionby a spring 35, the frame being provided with a cam 36, adapted toengage a cam face IOO or block 37, carried by the bevel-gear to effect alongitudinal movement of the gear, and the disengagement of the teeth ofthe wheels. At the inner end of shaft 3l is secured a hookclamping jaw38, the upper surface of which is arranged on the diametral line of theshaft 3l, and on the upper surface of said jaw is placed a hook-shapingplate 39 of the character more clearly shown in Fig. 6. The upper jaw 40of the clamp is provided on its under face with a hook-shaping plate 41,and the construction of such plates is such as to engage with andproperly shape the hook and to move the sections to be twisted intoclose contact with each other. The upper jaw 40 is movable with respectto the lower jaw 38 in order to permit of the insertion of a hook to beshaped and twisted; but when in the fullyclosed and clamping positionsaid upper jaw is coniined vertically by a stationary clamping-finger42, having an inclined lower face and adapted to coact with the inclinedupper face 43 of the upper jaw'.

On the under side of the jaw 38 is a depending bracket 45, to which isfulcrumed a lever 46, having at one end an operating-handle 47 and atits opposite end an upwardly-extending arm 48, in which is formed asegmental slot 49 for engagement with a pin 50, the latter being carriedby a link 51, swiveled to a lug 52 on the upper jaw 40. The lever 46 isprovided with a spring-carrying bracket 53, in which is seatedthelowerend cfa compression-spring 54, the upper end of said springbearing against the under side of the jaw 38 and the normal tendency ofthe spring being to close the jaws in clamping position. This closingmovement of the jaws is further assisted by a plate-spring 55, securedto the lower jaw and its upper end bearing upon the upper jaw, saidspring permitting of free lateral play of said jaw, but serving to holdthe jaws together while the hook to be twisted is being inserted betweenthem. In order to hold the jaws in the open position against the stressof the spring 54; I employ a springcatch 56, secured to the handle-bend47 of the lever 46 and adapted to engage with a handle 57, extendinglaterally from the upper face of the lower jaw and, as shown, formedintegral with the linger 42. The handles are normally separated, and thejaws are held in the closed position during the shaping and twistingoperation by the spring 54; but when a wire is to be inserted theoperator grasps and draws together the handles 47 and 57, permitting thespring-catch 56 to engage with the upper handle and hold the jaws in theopen position in kreadiness to receive a hook.

At a suitable distance from the end of the clamping-jaws and inalinement therewith is a vise, comprising a lower fixed jaw 60, securedto the frame, and an upper movable jaw 6l, having an arm fulcrumed to astationary arm extending from the lower jaw 60 or to any suitable pointon the fixed frame of the machine. rIhe jaws are normally held open by acoiled compression-spring 62, eX- tending between the pivoting-arms, andextending through openings in both jaws is a rod 63, forminga guide forthe spring 62 and having a securing-nut 64 at its upper end in contactwith the upper surface of the carrying-arm of the movable jaw. The lowerend of the rod 63 is connected to a suitable operating-treadle 65,fnlcrumed to a bracket 66 at the base of the framework and in convenientposition to be depressed by the operator to effect the closing of thejaws of the vise upon the portions of the wire to be twisted.

In the operation of the device the hook, as indicated in Fig. 6, isinserted between the clamping-jaws while the latter are in the openposition, (shown in Fig. 4,)the extreme end and the body of the wirebeing placed between the open jaws of the vise. The springcatch 56 isthen released and the 's prin g 54 acts through the lever 46 and itsconnections to move the clam pin g-jaws to the closed position, theshaping-plate 41 being moved toward the shaping-plate 39, longitudinalplay of such plates being prevented during this movement by theguiding-tongue 39 on the plate 3D and the guiding-recess 41 on the plate41. When these plates are in closed position, the hook is properlyshaped and the free end of the wire is bent in such manner as te forceitinto close contact with the main body of the wire. The operator thendepresses the treadle and firmly clamps the jaws of the vise on the thenparallel portions of the wire. The gear-wheel 33 then receives onecomplete revolution, either by manual or other power, revolving theshaft 3l and the clamping-jaw three times and making three completetwists in the wire, as shown in Fig. 1. The handles 47 and 57 are thenpressed together until the spring-catch 56 engages with the latter andholds the clamping-jaws in the open position. At the same time thepressure on the treadle 65 is removed, permitting the vise-jaws to openand release the wire. The fully-formed hook is then removed, and theapparatus is in readiness for the next operation.

. While the construction herein described, and illustrated in theaccompanying drawings, presents the device in its preferred form,- itisobvious that many changes in the form, proportions, size, and minordetails of construction may be made without departing from my invention.

Having thus described my invention, what I claim as new is-- l. In amachine for making bale-ties, the combination of therevoluble shaft, alower jaw carried thereby, an upper clamping-jaw movable with respect tothe lower jaw, shaping-plates carried by each of said jaws and adaptedto engage with and entirely surround the partly-formed hook, and a viseor clamp adapted to hold the ends of the wire during the rotations ofthe clamping-jaws, substantially as specified.
